The bring-it-back deal

The bottle comes back around.

Here's the whole idea. You don't throw the bottle away — you bring it back, we refill it, and you pay less every time. Cheaper for you, less trash, and it keeps your drink fresh.

  1. 01Grab your first bottle. Price announced at launch — no charge to reserve now.
  2. 02Drink it cold. Tart mixed berry, real ingredients, every dose on the label.
  3. 03Bring the empty back. Hand it over next time you grab one — that's it.
  4. 04Refills are cheaper. Every bottle after your first is a lower price, just for bringing it back.
Bring it back, pay less — it's that simple. The more you loop it, the more you save, and the fewer bottles end up in the trash. Regulars basically get a standing discount for doing the right thing.

Cold. Clear.

Who's behind it

Made by a
student who
needed it.

I'm Truman. I'm 21, I've got ADHD, and I got tired of picking between a $4 drink I couldn't handle and actually being able to sit down and study.

So I made the drink I wished existed — cold, clean, real ingredients, every dose on the label — and I'm building it so my friends can actually afford to try it. Then I built the bottle to come back around, so it stays cheap and doesn't pile up in a landfill.

This is the first batch, made right here in Rexburg. If that's a drink you'd want too, get on the list.
